INGLÉS

The present simple is used for:

Permanent states:

I am English (and I always will be English).
I work in Valencia (I do now and will do for the forseeable future).
I teach English.

Habits and routines:

I drive to work every day (it’s part of my daily routine).
I don’t wear white shoes (it’s my habit not to).
I like going to the cinema at weekends.

Permanent truths and facts:

New technology makes it easier to learn English.

It isn't always easy to see where one category ends and the next begins, but getting the verb into the right category isn't the objective here. Just remember that the present simple is used more than anything for facts and/or habits and/or things that are permanent. The category doesn't matter.
